NEW YORK (AP) _ Wall Street's angst over the ongoing fallout from the credit crisis made for a turbulent end to a volatile week Friday _ stocks tumbled, soared and then turned south again as investors tried to assess the dangers faced by the country's biggest mortgage financiers, Fannie Mae and Freddie Mac.

The Dow Jones industrial average, which traded down more than 250 points in the session, briefly moved into positive territory Friday before ending down more than 125 points. The blue chips also traded below 11,000 for the first time in two years. And all the major indexes ended with another losing week.

A new high for oil prices above $147 a barrel also weighed on stocks.

The fate of the government-chartered companies was a focus of trading Friday as it had been earlier in the week. Shares of Fannie Mae and Freddie Mac fell sharply over several sessions on concerns about their stability. Wall Street is worried that a collapse of the two financiers would cause further shock to the financial system, and trigger more losses to banks and brokerages with significant holdings of mortgage-backed securities.

Software problems bug Apple's launch of new iPhone

NEW YORK (AP) _ The launch of Apple Inc.'s much-anticipated new iPhone turned into an information-technology meltdown on Friday, as customers were unable to get their phones working.

In stores, people waited at counters to get the phones activated, as lines built behind them. Many of the customers had already camped out for several hours in line to become among the first with the new phone, which updates the one launched a year ago by speeding up Internet access and adding a navigation chip.

A spokesman for AT&T, the exclusive carrier for the iPhone in the U.S., said there was a global problem with Apple's iTunes servers that prevented the phones from being fully activated in-store, as had been planned.

Instead, employees are telling buyers to go home and perform the last step by connecting their phones to their own computers, spokesman Michael Coe said.

Reports: InBev, Anheuser-Busch talking

ST. LOUIS (AP) _ After weeks of public bickering, Anheuser-Busch Cos. Inc.'s board is likely to accept a sweetened buyout offer from the Belgian-based brewer InBev SA as early as this weekend, a published report said.

The Wall Street Journal reported Friday that InBev has boosted its takeover offer for the St. Louis-based maker of Budweiser, Bud Light and other beers by $5 a share to $70. It said one person it did not identify by name said the Anheuser-Busch board is likely to accept the offer this weekend.

An earlier New York Times report, also citing unnamed sources, said talks have become friendly. The Times also said Friday that a person close to the talks said Inbev had raised its offer to $70 a share. It said an announcement of a deal could come as early as Monday.

A deal would be a stunning turnaround from the often heated rhetoric between the two companies over the past several days.

In a 588-page federal notice, the Environmental Protection made no finding on whether global warming poses a threat to people's health, reversing an earlier conclusion at the insistence of the White House and officially kicking any decision on a solution to the next president and Congress.

The White House on Thursday rejected EPA's conclusion three weeks earlier that the 1970 Clean Air Act ``can be both workable and effective for addressing global climate change.'' Instead, EPA said Friday that law is ``ill-suited'' for dealing with climate change.

Trade deficit ebbs as exports rise to record high

WASHINGTON (AP) _ The U.S. trade deficit narrowed in May as exports _ including industrial supplies and consumer goods _ climbed to all-time highs.

The latest snapshot of trade activity, reported by the Commerce Department on Friday, showed that the nation's trade gap, thanks largely to the declining dollar, decreased to $59.8 billion. That was down 1.2 percent from April's trade deficit and was the best showing since March.

The improvement came even as imports _ including crude oil _ hit new record highs.

The trade deficit narrowed in May because exports grew fasterthan imports.

The Dow fell 128.48, or 1.14 percent, to end at 11,100.54 after having fallen to 10,977.68. It last traded below 11,000 on July 25, 2006.
